Sensitivity to Light after LASIK

By Dr. David Masihdas on December 03, 2016

Fingers held in a square shape around the sunIf you're tired of wearing glasses or contact lenses to improve your vision, you may be considering laser vision correction, or LASIK. LASIK surgery can help those who have myopia, hyperopia, or astigmatism to enjoy improved vision without the need for contacts or glasses. Although LASIK surgery is safe and effective, it is associated with some risks and potential side effects. During patient consultations, Dr. David Masihdas explains the possible risks and side effects of LASIK surgery, one of these being sensitivity to light after LASIK. To learn more about your potential risks and side effects, including sensitivity to light after LASIK, we welcome you to schedule a consultation at our Salt Lake City, UT practice.

Increased Sensitivity to Light after LASIK

Patients who undergo LASIK should expect to experience some side effects. One of the most common side effect is increased sensitivity to light. For most, increased sensitivity is usually mild and short-lived. Many find that the sensitivity subsides or fully resolves within a few days to a week.

What Causes Increased Sensitivity to Light after LASIK?

It's not uncommon to experience increased sensitivity to light after LASIK surgery because the eye must adjust to its newly shaped cornea. The eyes become accustomed to processing light through an abnormally shaped cornea; a change to the shape of the cornea can cause the eyes to be more sensitive until they adjust. Fortunately, most people who experience increased sensitivity to light after LASIK surgery will find that their vision returns to normal within a short time.

In addition to adjusting to corneal shape, some other causes of increased sensitivity after LASIK surgery include:

  • Corneal swelling: LASIK surgery can cause the corneas to swell. Swelling, even in the corneas, is a natural part of the healing process, but it can cause an increase in sensitivity to light until it resolves.
  • Dry eye syndrome: Temporary dry eye syndrome is a common side effect of LASIK surgery. It can also cause the eyes to feel more sensitive to light. Dry eye syndrome generally resolves as the eyes recover but can be alleviated with eye drops as recommended by your doctor. 
  • Blade-free LASIK technology: Blade-free LASIK surgery, which uses only lasers to correct vision, is a safe method of reshaping the cornea; however, it does carry a higher risk of transient light sensitivity (“TLS”) than LASIK performed with a blade. TLS is easily treated with medication and will resolve as the eyes recover.

Candidates for LASIK Surgery

Although LASIK surgery carries some risk and potential side effects, the benefits of clearer vision make it well worth it. Ideal candidates for LASIK surgery include those who are:

  • Over 18
  • Free of serious eye problems such as glaucoma, cataracts, injury, or infections
  • In good general health
  • Not pregnant or nursing
  • Does not suffer from dry eye
  • Experiencing stable vision, with a prescription that has not changed for at least one year
